UNITED STATES PATENT OFFICE.

JAMES NATHAN BATTS, OF COAL VALLEY, WEST VIRGINIA.

SCRUBBING-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 368,052, dated August9, 1887.

Application filed September 18, 1856. Serial No. 213,925. (No model.)

To all whom, it may concern,.-

Be it known that I, JAMEs NATHAN BA'rTs, a citizen of the United States,residing at Coal Valley, in the county of Fayette and State of WestVirginia,I have invented a new and'useful Improvement inScrubbing-lliachines, of which the following is a specification.

My invention relates to an improvement in scrubbing-machines; and itconsists in the peculiar construction and combination of devices, thatwill be more fully set forth hereinafter, and particularly pointed outin the claims.

In the drawings, Figure lis a perspective view of a scrubbing-machineembodying my improvements. Fig. 2 is avertical longitudinal sectionalview of the same.

A represents a car, which is provided on its under side with cross-barsB. To the ends of the said cross-bars, on the under sides of thesame,are pivoted casters C, in which are journaled rollers D, that bearupon the floor and support the car and enable the latter to be moved inany direction. In the rear portion of the car is made a seat, E, for theoperator, and in the front end of the car is a compartment or box, F,which is water-tight and is adapted to receive the suds to be used inscrubbing the iioor. This box or compartment is provided on its upperside with a hinged lid, G.

H represents a crauk-shaft,'which is journaled in bearings I,that aresecured to the upper edges of the car at a suitable distance in front ofthe seat E, and to one end ofthe crankshaft is attached a crank-wheel,K.

L represents a rock-shaft, which is journ'aled in bearings M at thefront end of the car,nearits lower side. The said rock-shaft is providedat its centervwith a crank, L, and at one end with a crank-arm, L2. Thislatter is connected to the crank-wheel K by means of a pitman-rod, N,which is provided near its upper end with a slot, M, in which works thecrank-piu O,that projects from the crankwheel K.

From the foregoing description -it will be readily understood that whenthe crank-shaft H is rotated the shaft L will be rocked or osoillated. 1f

The function of the slot M is to cause the shaft L to dwell or remainstationary twice at each rotation o f the crank-wheel while thecrank-pin O is passing the dead-center, to the end thatthe'scrubbing-brush hereinafter described will be caused to rest on theiioorduring a short period at the end of each stroke.

E representsaspring-rod, which` is attached at its inner end to thecrank L. This springrod is guided by a keeper, S, on the front end ofthe car, and projects forwardly therefrom, and the outer end of thespring-rod is pro vided with a transverse notch, R.

T represents a scrubbing-bush,on the upper sideof which is made atransverse recess, ,T, adapted to receive the frontend ofthe springrod,and the said scrubbing-brush is also provided on its upper side with ahinged strap, T2, which is adapted to close over the front end of thespring-rod and. rest in the notch thereof, and the free end of the strapis secured to the scrubbing-brush by means of a catch, T3. By this meansit will be readily understood that the scrubbing-brush may be firmlyatt-ached to the front end of thespringarm or disengaged. therefrom. Inthe lower side of the sudsbox F is a pipe, U, which project-s forwardlyfrom the car, and the inner end thereof is open and communicates withthe interior of the suds-box. A stop-cock, V, is provided for the saidpipe, and the stem V thereof projects upwardly through the Ycover of thesuds-box, and is provided at its upper end with a suitable handle,bymeans of which the stop-cock may be turned so as to permit water in thesudsbox to be discharged upon the floor through the pipe U.

The operation of myinvention is as follows: In order to scrub a iloor asuitable quantity of suds is poured into Athe suds-box and thescrubbing-brush is attached to the spring-rod. The operator is thenseated on the seat E and grasps the crank-shaft II and rotates the same,thereby communicating an oscillating motion to the shaft L and causingthe scrubbingbrush to be reciprocated back and forth in front of the carin contact with the iloor. A suitable quantity of suds is dischargedupon the iioor through the pipe U, and the reciproA eating motion of thescrubbing-brush is maintained a sufficient length of time to cause it tothoroughly scrub the iioor at that point. A pushing pole or lever isgrasped by the oper- IOO ator in the ear, and the end thereof is restedagainst the floor or wash-board, and by pressing upon the same the earmay be moved to any point of the floor desired.

From the foregoing description it will be readily understood that theoperator is entirely protected from contact with the fioor while thescrubbing is being done, thus rendering it impossible for her feet toget wet, and avoiding the danger of contracting colds or rheuniatism.

Having thus described my invention, I claim l. rlhe combination of thecar, the crankshaft II, journaled thereto and having the crank-pin O,the rock-shaft L, the scrubbingbrush connected thereto and operatedthereby, the said rock-shaft having the crank If, and the pitinan N,connecting the latter with the crank-pin O, and having the slot M,inwhich the said pin slides, for the purpose set forth, substantially asdescribed.

2. The combination of the ear, the rockshaft journaled thereto andhaving the cranks L and L2, the bar R, pivoted to the crank L and havingthe scrubbing-brush at its outer end, and the crank-shaft II, journaledto the ear and connected to the crank L2 of the roekshaft, whereby thelatter may be oscillated, for the purpose set forth, substantially asde'- scribed.

8. The combination of the car having the supportiiig-rollers, thesnds-boX, and the seat, the rock-shalt L, journaled to the ear andhaving the cranks L and L2, the rod It, connected to the crank L andhaving the scrubbingbrush at its outer end, and the crank-shaft Il,

ionrnaled to the car and having the crankwheel K, and the pitman-rodconnecting the said crank-wheel with the crank Iil of the rockshaft, forthe purpose set forth, substantially as described.

4. The combination, in a scrubbing-machine, of the rock-shaft having thecrank-arni, andthe spring-rod It, attached to the said erankarm andcarrying the scrubbing device, substantially as described.

5. The combination ofthe rod l?, having the notch R at its front end,with the scrubbing-brush having the notch 1" to receive the front end ofthe bar,and the locking-strap T2, to enter the recess R and secure thescrubbingbrush to the spring-bar, substantially as described.

In testimony that I claim the foregoing as my own I havehereto affixedmy signature in presence of two witnesses.
